Re: [K3] [Elecraft] Questions about ARRL review

disc ceramic capacitors - bad for IMD! If there is a problem with those capacitors at 30dbm, I am wondering about the power amps especially SS where ceramic caps are used extensively. Seems nearly all amp's IMD cam generated in those caps. Am I missing something? Ignacy -- View this message

Not all disk caps are the same - it depends on the dielectric. NP0 types are pretty good but the high K formulations, Z5U and Y5U are not so good. I've written about capacitance versus voltage and harmonic distortion in various dielectrics at

Thank you Lyle. It never occurred to me that this was purposeful. I adjusted the filter offsets with the 500 and 200hz filters to more closely center them. Guess I'll believe the factory settings from now on! tnx, Gary W7TEA This asymmetry is due to the way in which the K3 aligns the
